FLEXIBLE STEEL RULE GAUGE File-d Dec. 51,1194@ /a EL( A torney v Patented Sept. 23, 1941 UNITED STATES PATENT OFFICE 2 Claims.

The present invention relates to new and useful improvements in gauges and more particularly to a slide gauge for flexible steel rules.

The principal object of the present invention is to provide a gauge which can be readily applied to a iiexible steel rule and which is adapted to be slid to any desired graduation and there firmly secured against accidental adjustment.

Other objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawing:

Figure 1 represents a fragmentary top plan view of 4a exible steel rule with the gauge'applied thereto.

Figure 2 is a fragmentary detailed sectional view taken substantially on a line 2--2 of Figure 1.

Figure 3 is a cross sectional view taken substantially on a line 3-3 of Figure 1.

Figure 4 is a top plan view of the gauge block with the plate removed.

Referring to the drawing, wherein like numerals designate like parts, it can be seen that numeral 5 denotes a flexible steel rule of the rollable type and which is usually of transverse curvature.

The gauge comprising the present invention is generally referred to by numeral 6.

The gauge is composed of a block 'I of rectangular shape and having an arcuate-shaped cutout 8 in the intermediate portion of its top. A small groove 9 is provided across the bottom of the cut-out 8.

Rising from each end portion of the block 1 are pins I which project into openings in plates II and I2. Of course, these pins III can be carried by the gauge plates II and I2 and depend into openings I3 in the block 1.

The gauge plate Il has an opening therein for receiving a wood screw III which is driven into an opening I in the block 1, while the plate I2 has an opening therein registrable with the opening I6 in the block 'I to accommodate a bolt I'I. A knurled nut I8 is provided on the upper portion of this bolt I'I and can be screwed downwardly to bind against the plate I2. Obviously, the pointer protruding portions I9 project over the edge portions of the rule 5 and the rule is free to be moved in the cut-out 8 under the projections I9 when the nut I8 is in loosened position. vI-Iowever, when the nut I8 is tightened down onto the plate I2, the rule is clamped against the bottom of the cut-out 8 and between the pointer projections I9.

Obviously, the gauge in conjunction with the rule can be used as either an outside or inside caliper.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new isl. A gauge for iiexible steel rules comprising a block having a depression therein through which Ia exible steel rule is movable, plates on the block having portions projecting over the edge portions of the rule and means for tightening and loosening one of the plates with respect to the corresponding edge of the rule.

2. A gauge for flexible steel rules comprising a block having an arcuate depression therein through which a flexible steel rule is movable with its edge portions at the top of the depression,

. plates on the block having portions projectingr over the edges of the rule and means for tightening land loosening one of the plates with respect to the corresponding edge of the rule, said means consisting of a bolt extending through the block and the last-mentioned plate and provided with a nut on the plate end of the same.
